An extendable trailer configuration is a trailer mechanism that is designed and adapted to be towed through the use if a tractor truck travelling along a roadway.The extension on the trailer is done efficiently take loads that may be of different lengths as the job will demand.
The transportation industry has different types of vehicles and platforms that are used to meet different demands and needs. One such means of transportation used is the extendable trailer. Just like is the case with other means of transportation, this type of trailer is suited for certain applications that would otherwise not be addressed through the use of other types of transportation platforms and/or vehicles.
Longitudinally extendable is commonly used to transport very long cargo, like tanks and windmill blades and bridge sections among other similar-like cargo.
To take these loads, the trailer is extended lengthwise. When it is not carrying any load, it needs to be adjusted back to a short length. Its application and use should, however, be based on the stipulated local laws and driving safety.

Key Components of the Extendable Trailer.Here is a detailed look into how each of these parts are adapted to function:
The extendable trailer frame construction features the main beam, half plates to the left side and the right side and a transverse device. The half plates to the left and right side are linked to the main beam by means of the transverse device. The hydraulic gooseneck is attached to the frame head and a hydraulic ladder fitted at the rear section.
The assembly and connection at the gooseneck point is usually made to the tractor saddle via the turntable, the wedge and the traction pin. The extendable trailer’s gooseneck feature is a hydraulic part that is usually adjusted through a telescopic expansion of the hydraulic cylinder.
As the tractor rotates, the steering cylinder gets pushed and transmitted to the steering bridge of the trailer via the hydraulic circuit. The steering mechanism towing the extendable trailer is usually attached in the gooseneck.
The basic components of the hydraulic system are hydraulic valve blocks, joints and pipes. The entire system comes with a hydraulic source by means of a power unit. There is also a safety valve installed in the circuit.
The trailer has a hydraulic system that comprises control circuits like the suspension lifting, gooseneck lifting, synchronous steering, lateral adjustment and in lifting the ladder.

The steering system of an extendable trailer comprises a wheel steering mechanism, gooseneck steering mechanism and a matching hydraulic synchronous control circuit.
The gooseneck steering mechanism makes use of the tractor’s rotation in relation to the trailer in order to contract and expand the steering cylinder in a synchronous manner in relation to the wheelset steering mechanism.
This then drives the axle via the steering rod and the turntable.
To further enhance swift operations with the extendable trailer, a braking system is provided. This includes a service brake, a dual-line automobiles brake system and a parking brake.
An emergency relay valve, air reservoir, double-brake chamber and a number of specifications for the components connecting to the pipeline.
The supply and control lines are set separately. The most significant components include a connector attached to the tractor.
The power unit is made up of a small diesel engine, which is the main prime mover. Other components include a hydraulic oil tank, control lines and pipelines, hydraulic pump. The unit offers a hydraulic source for the trailer’s hydraulic system.

A 24V single wire system forms the electrical system of the extendable trailer. In totality, the electrical system includes lights, connectors and wires among other components.The electrical connection attached to the tractor chosen is the national standard 24N type electrical connector.
The external signalling and lighting components are usually provided with brake lights, rear position lights and position lights among other as deemed useful for use in this application.
Due to the varying demands of cargo in terms of size, particularly on its length and width, the need for establishing a lasting solution led to the making of extendable trailers.We can also custmize it for you according to your requirement.
